k Application filed November To all whom it mdy concern:

Be it known that I, JACOB J. BYEns, a resident of Chicago, in thecounty'of Cook and State of Illinois, have invented a new and usefulImprovement in Car-Trucks, of which the followin is a full, clear, andexact description, re erence being had to the accompanying drawings,forming part of this specification, in which.

F i ure l is a side view of a portion of the side rame and one, of thejournal boxes of a car truck and illustrating my invention; F ig. 2 is asection on theline II-II of Fig.

1; and Figs. 3 and dare views similar to Figs. 1 and 2, respectively,but showing a modification. I a

My invention has relation to car trucks, and more particularly to meansfor securing .the journal boxes to the side frames, the

object of my invention being to provide a simple and convenient securingmeans whereby both vertical and horizontal movements of the boxes withrelation to the .side frame are revei'ited, and which is provided withasaleguard for holding the parts in proper relation, in. case thesecuring nuts should become loose or workoff.

Referring to the drawings, the numeral 2 designates the side frame of acar truck. which is provided at the end with an overhung extension 3 toreceive the journalbox 4, the under side of this extension beingprovided with a horizontal bearing face 5, for the top of the box andthe end of the side frame preferably being provided with a bearing face6, at substantially right angles to the bearing face 5, and theboxfitting in the angle between these two faces.

7 is a strap bolt by means ofwhich the box is secured to the frame. Thisbolt extends downwardly through the end of the overhung extension 3,around and underneath the box, its lower end being provided with a head8, and its upper. end being provided with a threaded portion 9, toreceive a holding nut 10. Inasmuch as the nut 10 may, in practice,become loose or work ofi,

l in order to hold the parts in secure relation in such a case, Iprovide the bottom. of the box with an eye 11,.through which the lowerhorizontal-arm of the bolt is passed. In this manner, the parts are heldsecurely in' place, notwithstanding the looseness or loss of the nut 10.

The box is shown as having lateral and bottom flanges 19, forming agroove to reis convexed, the strap bolt being bent to conform to thecurvature of the lower outer portion of the box, so that when the boltis tightened, it tends to draw the box both upwardly and also inwardlyinto contact with the bearing faces 5 and 6, thus preventing anylooseness;

In Figs. and 4, I have shown a modification in which the strap bolt 7 isof flat form, with rounded end portions. In this form, the bottom of thebox is formed with a retainer 14- for the strap bolt. This re tainer isshown as formed by thelugs 15. It will be obvious that the strapbolt-may be of various forms, and that the retainer therefor may beformed in various other ways. 7

Features of my invention which are herein shown but not claimed form thesubject matter of another pending application.

I claim: 1. A journal box for car axles having a to prevent droppingaway of the securing device, substantially as described.

2. In a car truck, a side frame having a seat for a journal box open atone side and at the bottom, a journal .box havinga retainer 'onitsbottom portion, and a strap or boltpassing through said retainer andsecuring the box to the side frame, substantially as described.

3. In acar truck, a side frame having an overhung end portion, a journalbox seating underneath the ove rhung portion and against the end of theside frame and havceive the strap bolt, and its lower portion 13retainer at its lower portion to receive a securing device, saidretainer being arranged With a retainer arranged to receive a securingdevice and hold it agaimt dropping 1) away; substantially as(i(,$-('1'l|)0(i.

In testimony )vhereof, I have hereunto set my band.
